T 0 @lll/whom 'it may concern.' y y Be. it Aknown that l, THOMAS"liIoLLora a- Vcitizen of the UnitedStates, and resident of Roxbury, county ot Suffolk, State ot Massachusetts, have invented an Improvement in riobacco Pipes, ot` which the following description, in connection withthe accompanying drawing,is a specification, lilre characters on the drawing represen-ting'lilreparts This invention relates to tobacco 1 lpipes and has tor ,its general object yto providea 'novel pipe constructionV by which the moisture and nicotine will be trapped before' it reaches the end otthe pipe stem so that the t smoker will always enjoy a dry smoke.

In order to give an understanding of my invention i have illustrated in the drawings a selected embodiment thereof which will now be described after which the novel teatures will be pointed out in the ap'pende claims.

ln the drawings,' Fig. 1 is a vertical sectional view through a pipe embodying my invention.

`Fig. 2 is atop plan view.

The pipe shown in the drawing comprises the usual bowl 1 and stem 2. This stem is made in sections, one Section 3 being integral with Athe bowl 1 and the other section 4 constituting the moutn piece and being detachable. T he two sections are connected together by aconnecting member 5 which is provided with two bosses 6 that enter recesses formed in the ends ot the stem sections 3 and il. The stem sections 3 and 4 are provided with the usual duct 7 and the connecting section 5 is also provided with aV duct S extending therethrough which is situated in alignment with the duct 7. y Y

in order to provide a construction which will trap any moisture or nicotine that tends to be drawn through the smolre duct I propose to form the. stem with two chambers 'communicating with the duct and which are connected by a by-pass situated above` the pipe stem. The chambers have absorbent material therein and when in use the smoke will be drawn from one chamber to the other around through the by-pass and any moisture or nicotine will-become trapped in the chambers and will be absorbed by the absorbent material. These two chambers are shown at 9 and 10 and they are positioned either side ot the connecting member in fact the chambers form eontinuations of the recesses in the stem sections into which the bosses 6 of the connecting member are received. The by-pass connecting the chambers is indicated at 11 and is formed in U- shaped tubular member having its ends received in apertures formed in the stem seetions 3 and L1. This by-pass is preferably formed with a chamber 12 which may have absorbent material 13 situated therein. Each vot the chambers 9 and 10 also has absorbent material therein as shown at 1.5 and such absorbent material is forced firmly into the duct S so that the smoke cannot be readily drawn through said duct. On the other hand the absorbent material 13 in the chamber 12 will be loosely placed therein so that the smoke may be easily drawn therethrough. Y

When the pipe is in use the smoke from the bowl will be drawn through the stem section 8 into the chamber 9 and thence around through the by-pass 11 into the chamber 10 and thence through the stem section 4. The smoke will take this course because the density of the absorbent material in the duct 8 is much greater than that in the chamber 12, and the by-pass presents much less resistance to the passage of the smoke than the duct 8 itself. lt any moisture or nicotine tends to enter the duct 7 it will become trapped in the chamber 9, because of the tact that the by-pass 11 enters the topv ot the chamber and the smoke will readily pass upwardly into the by-pass while moisture and nicotine which is heavier will accumulate in the bottom of the chamber 9 and willbe absorbed by the absorbent material. lt there should be any condensation at the delivery end ot the by-pass the moisture will collect in the chamber 10 and will be absorbed by the absorbent material therein.

The by-pass pipe is removable from the pipe stem, the ends of said by-pass pipe being freely withdrawable trom the apertures in the pipe stem. This by-pass pipe is also shown as made in two sections 16 and 17 `which are detachable from each other at the chamber 12 thereby providing for renewing the absorbent material 13. y

vThe by-pass pipe is shown as having an enlarged central portion 18 within which the chamber 12 is formed Vand the joint between the two sections 16 and 17 is located at this chamber. Each section has an enlarged end and one section has a recessY into Which a. lip 19 on the other section 1s re ceived.

Whenever it 1s desired to reneW Vthe absorbent material V it is simply necessery to irst remove the bly-pass pipe 11 and then l to separate the mein sections 3 and l and re is doneV the absorbent materiel 15 een be nove the connecting section 5. VVhen this readily removed ifrom the connecting section vandiresh absorbent material put in place after which the parts may be assem bled. 'Y

My improved pipe is sanitary and it also will operate to prevent the passage of lany nicotineor moisture through the stem secn tion-4:. Y Y
